Abstract
Purpose: To assess the therapeutic value of two different drainage catheters in
treating chronic subdural hematoma (CSDH). Materials and Methods: Two types
of drainage catheters can be used to treat CSDH according to the position of holes
in the catheter: open-type or closed-type catheter. In this retrospective study, 199
total patients with CSDH were reviewed according to catheter type. Among them,
84 patients were and 113 in the closed-type group (holes positioned within the distal-most
1 cm of the catheter). The surgeon selected the catheter type. Total drainage
volume, initial drainage volume within 2 days, percentage of initial drainage
volume per total drainage volume, duration of catheter insertion, and reoperation
rate were compared. Results: Total drainage volume was not different between the
two groups (p=0.333). The initial drainage volume within 2 days was larger in the
open-type group than closed-type group (p=0.024), but the percentage of initial
drainage volume per total drainage volume was not different (p=0.354). The duration
of catheter insertion was shorter in the open-type group than closed-type
group (p=0.015). The reoperation rate of CSDH was also higher in the open-type
group than closed-type group (p=0.004). Conclusion: CSDH drainage with an
open-type catheter is faster compared with a closed-type catheter, but total drainage
volume is similar and reoperation rate is higher. Therefore, the open-type catheter
for CSDH drainage has limited clinical value.
